33 Claims.

This invention pertains to improvements in the .paper holding, paper feeding, and printing mechanisms for adding, calculating, and accounting machines of the type providing multi- 5 ple and selective column printing, using, to achieve this result, multiple groups of printing elements requiring no relative lateral movement between 'the record material and the said printing elements. The machine used for the purpose l of this disclosure is described in United States Letters Patent No. 1,685,685 and Reissue No. 20,167 of the same patent. granted to Abraham Smith on September 25, 1928, and November 10, 1936, respectively. To a large extent, the paper l holding and paper feeding mechanism herein described is disclosedin the application for United States Letters Patent, Serial No. 653,838, filed by Raymond A. Christian on January 27, 1933, and in British Letters Patent No. 424,132 issued to 'I'he National Cash Register Company on February 15,

The principal object of this invention is to provide a machine of the Smith type, above mentioned, with means for rocking the platen away from the printing elements to front-feeder open- `throat position, so that paper or other matter may be inserted between the platen and the,

printing elements, from the front of the machine. Another object of the invention is to provide sucha machine with means for automatically rocking the platen open to front-feed or openthroat position at the end of a series of printing or recording operations or at the end of a machine operation when manually determined at the '35 beginning of such machine operation.

A further object of this invention is to provide such 'a machine with ak disabling mechanism for the automatic column selecting device and a platen rotating mechanism, so that successive n printings or recordings may be made in a single vertical column.

A further object of this invention is to provide a positive, automatic locking mechanism for the printing hammers of the groupscf printing elements that are to be inoperative during a particular machine operation. With these and incidental objects in view, the invention includes certain novel features of con- .)0 struction and combinations of parts, the'essential elements of v which are set forth in appended claims and a preferred form or, embodiment of which is hereinafter described with reference to the drawings which accompany and form a part 55 of this specification.

A transverse rock shaft 30 (Fig. l) is driven by hand or motor in a counter-clockwise and then v a clockwise direction during one machine opera' tion. To the rear of rock shaft 3|l and parallel to it is a second transverse shaft 3|, which will hereafter be referred to as the main drive'shaft." Rock shaft 30 has an upwardly extending arm 32 secured to it, and a stud 33 extending from the arm 32 into a slot 34 inl link 35 connecting the arm 32 with a similar arm 36 secured on main drive shaft 3|. Spring 31, connecting stud 33 and link 35, affords a gradual application of force from arm 32 to link 35,-while stud 33 moves counter-clockwise during the rst half of the machine operation and finally makes positive contact at the forward end of the slot 34 with link 35 to move it forward. On the second half of the machine operation the arm 32 moves clockwise,vflrst allowing link 35 to move to the rear and then forcing it to the rear as stud 33 contacts the rear end of slot 34. Link 35, through pivot 38 and arm 36, imparts oscillating motion to the main drive shaft 3|, rst counter-clockwise and thep clockwise, during one machine operation. Fast to the main drive shaft 3| is an arm 38 having a toothed edge adapted to cooperate with a pawl (not shown) to require'a complete oscillation of the mechanism once a machine operation has started.

Type selecting mechanism A transverse shaft 40 (Figs. 1, 2, 3) has pivoted thereon a number of type bar levers 4| (Figs. 1, 2, 3) having rearwardly extending por. tions 42 fastened to individual springs 43 tensioned to constantly endeavor to 'cause the type levers to turn clockwise on shaft 40 (Fig. 1). The type bar levers, twenty in number, are divided into four groups of ve levers each. The four groups represent four printing columns. It will be shown later that any one group can be made responsive alone to the keys depressed, so that the printing may be done in any column, while the other groups will be locked against printing.

The five type bar levers in each group representdecimal orders (Fig. 2).

Arranged onfthe upwardly extending armsof the type bar levers are plungers 41 (Figs. 1 and 3) bearing type on their rear ends and adapted to be struck by printing hammers 48 (Fig. 1), there being oneprinting hammer for each group of type bar levers. The individual type plungers are numbered with digits in vertical order, so

that clockwise 'rotation of a type bar.lever on shaft .48 would cause successive numbers to come into printing position'.

The type levers; are held against clockwise rotation by bails 49 (Figs. 1, 21, 3) pivoted on shaft 40. 'I'hese balls are flve in number and represent the live decimal orders in each group. The bails do notl rest directly on the type bar levers, but on fingers 60 (Figs. 1 and 3) projecting upwardly froml the type bar levers. The lingers on the type bar levers of the decimal order of tenths, for instance, will be alined to hit the under side of the bail representing tenths. Only one lever in each group rests on any one bail. Consequently, if the tenths bail were allowed to rotate clockwise, all the type lever bars of the order of tenths would be permitted to follow, and would follow, because of the tension of springs 43. The same is true of any of the orders. If the hundreds bail is lifted, the hundreds order type bar lever in each group would rise. The ngers 60 allow such selected type lever motion without interfering with the bails of another decimal order.

Provision is made for locking groups of type levers unwanted in a particular operation, in their lowest or home position. by hooks 6| (Figs. l and 4) on the -under side of each type bar lever, so that only a selected group or groups will respond to the raised bails 49. The arms of balls 49, which are pivoted to shaft 40, are portions of bell crank levers whose lower extending arms 62 (Figs.

1 and 3) arealso joined by balls 63 (Fig. 3).,

Each of the balls 63 has one rearwardly extendingflnger 64 (Figs. 1 and 3) joined to its own key -actuated lever 65 (Figs. l, 2, 3) by a pivotal connection 66 (Figs. 1 and 3). The position of linger 64 for the hundreds bail is directly to the rear of the corresponding row of keys on the keyboard.

As set forth more fully in the Abraham Smith patent heretofore referred to, the keys determine the positioning of links- 61 (Figs. 1 and 3),

which links, through pivotal connections 68 (Fig.

1) and levers 65, set their respective bails to the selected position. If the hundreds key 8 is depressedand the machine operated, the corresponding link 61 will move forward, the hundreds lever 65 will cause the bell crank lever 62 corresponding to the hundreds order to rotate clockwise, and all the fingers 60 of the hundreds .order will tend to follow their ascending bail and will be stopped when the type plungers bearing the digit 8 are in printing position. The 8s in all four `groups representing the hundreds order will come to printing position unless retained by hooks 6| (Figs. 1 and 4). The same principle applies to each row of keys and their corresponding bails.

It is apparent that any symbols may be used on the keys and type faces, and that the number of orders in the group or the number of groups may be'varied. It is also obvious that the groups of type lever bars need not be spaced uniformly and may be moved to any position laterally to accomplish the purposes to which the machine is put.

The re is a sixth bell crank bail 69 (Figs. 1 and 2), which acts as a locking device forall the type lever bars when the machine is inoperative. A pair of plate cams 10 and 1| (Figs. 1 and 2) secured' on the main drive shaft 3| is shown in home position and by cooperating with rolls on the locking'bell crank bail 69 holds said Attached to th left side of ,the casing is a stud 12 (Figs. 1, 2, 6) on which is rotatably mounted a gear wheel 13 carrying a ratchet 14 operated by a pawl 15 carried by an arm 16 pivoted on stud 12. A spring 18 (Fig. 6) serves to keep the pawl 15 constantly engaged with the ratchet wheel 14, so that counter-clockwise motion of arm 16 allows the pawl 15 to ride `over the ratchet teeth and clockwise motion causes the ratchet and attached gear wheel 13 to be turned in a clockwise direction. The motion necessary to accomplish Athat result is obtained from the cam plate 1| on shaft 3l, through a link 11 pivotally mounted intermediate arm 16 and cam plate 1| (Figs. 2 and 6). Cam 1I. turning counter-clockwise on the first half of the operating cycle, causes the link 11 to turn arm 16 and pawl 15 counter-clockwise, and on the second half of the cycle to return the arm 16 and the pawl 15 to normal and thus turnA the geared wheel13 clockwise 45 degrees. Wheel 13 is geared to another wheel 19 (Figs. 1, 2, and 4) which is one half the diameter of gear wheel 13, and is secmed on a transverse shaft 80 (Figs. 1, 2, 4), which shaftv 80 is thus turned 90 degrees counter-clockwise for each operating cycle of the machine. On the shaft 80 are four cams 8| (Figs. 1, 2, 4), spaced, one in front ofeach group of type bars, and the operative surface of each cam is turned 90 degrees from that o f its neighbor in .spiral fashion. These cams are designed to contact locking pawls or hooks 82 (Figs. 1 and4) pivoted on a transverse lshaft 83 and drawn yieldingly in a counter-clockwise direction by springs 84 (Fig. l) The upper ends of the pawls engage the hooks 6|^ on the under side of the type b ar levers, one vpawl 82 locking`v all the levers 4| in onev group and one cam 8| serving to unlock the pawl it serves -once in every four successive'machine operations. The

result of this is that, in the particular arrangement shown, only one type group is permitted to be set to printingposition by the keys in a given machine operation. As the shaft 83 can be manually set to one of four places by turning a knob fastened to it, the operator can dtermine in what column the irst printing shall take place. Fig. l2 shows the alining device for accurately setting the cams either by hand knob 85 (Fig. 2) or by the gear .19. If desired, Athe hand knob may be furnished with a locking pawl to prevent movement of the gears in a direction reverse to that given in regular machine operations.

ranged on the shaft so that the type lever groups may be unlocked in any sequence, or in groups, or in sequence ,of groups. It will be obvious also that if the gear 19 is splined on shaft 80 so that shaftmay be shifted laterally, an auxiliary set of cams could be provided and shifted to the operating plane of the locking pawls.

Fig. 4 shows the second cam from the left unlocking the pawl from thessecond group of type levers, and'therefore the machine Ais conditioned to print in the secondvcolumn from theleft. i

Vertical printing A method for enabling the machine to print successive transactions, one below the other in the same column, is one of the novel features comprised in this invention. On shaft 12 (Fig. 6) is pivoted a bellcranklever 86 (Figs. 2 and 6) having on one arm-thereof a cam projection 81 (Fig. 6) designed to lift pawl 15 fromengagement with the ratchet wheel 14. A single column key, so marked in Fig. 6, is depressible, and, in being depressed, rocks bell crank lever 88 counterclockwise, which moves link 89 to the rear, causingbell crank lever 86 to turn clockwise, thus disengaging the pawl 15 as desired. The column selecting eam shaft thus disabled will not then automatically make .a quarter turnat each operation of the machine. Provision isv made for turning the platen on its axis to line-space the -record material for each printing cycle when the single column key -is depressed. The lower extending arm of bell crank lever 86 is attached' to a plate |00 (Fig. 6) .having a bifurcated portion enabling the plate to move backward and forward on main drive shaft 3|. The plate |00 has a rearwardly projecting arm equipped with wheel.

It is apparent that the cams 8| may be arl a stud |0| which, when plate |00 is'in the rearward position, holds link |02 from being engaged and moved by stud |03 oi cam 1|. When the single column key is depressed and plate |00 is drawnforward, the link |02 is engaged by stud |03-as cam 1| is raisedon the ilrst half cycle of operation, and, on the downward motion of the cam 1|, the link |02 is drawn down A by stud |03, which causes bell crank lever |04 to turn clockwise on its pivot |05, said pivot being the rock shaft for the platen assembly to be described.

Reference will now be made to Fig. "7, showing an enlarged view of the upper half of Fig. 6.`

Clockwise movement of bell crank lever |04 pulls link |06 to the rear, the other end of which is pivoted at |01 to an arm |08 pivoted on the platenv shaft |09. On shaft |09 is secured a toothed ratchet wheel ||0' which is engaged by a pawl attached to arm |08. Spring ||8 holds pawl in engagement with the ratchet Spring ||2 tends to hold arm \|08 in counter-clockwise position. When bell crank lever |04 turns clockwise, link |06 moves to the rear and causes arm |08 and pawl to turn clockwise, which turns the platen shaft and platen ||3 clockwise. Counter-clockwise motion of bell crank lever |04 allows spring ||2 to cause the arm |08 to'resume its former position, ready for the next machine operation.

The number of spaces the' paper advances through clockwise rotation ,of the platen is d'etermined by a plate cam I|4 pivoted on shaft |09 beside theratchet wheel ||0, which cam, through an elevated periphery- I5, holds the pawl away from the ratchet wheel, making the motion of link |06 ineffective through a determinable part of its movement.

The turning of cam 4 on the shaft |09 by hand lever ||6 causes teeth I|1 to engage an alining pawl (see Fig. 6) for accurately positioning the cam. Continued movement clockwise of the pawl will cause it to reach the end of the elevated part of the periphery of cam ||4 and by the action of spring ||8 it will be pulled to engagement with the ratchet teeth'. Teeth '||1 are cut to make the platen movement one, two, or more spaces. Clockwise movement of plate ||4 causes the paper to advance a lesserrnumber of lines. v

Because. the platen |I3 and'its supporting frame ||9 rock open clockwise around shaft l|05, and bell crank lever |04k remains still,'being only pivotally mounted on shaft |05, the link |06 will travel to the rear, leaving stud |20 in the for- 55 ward end of the/slot. Clockwise motion of 'lever |04 will then be ineffective to move the pawl ||I, because stud `|20 will play idly in its slot.

As the platen rocks open on. the same halfcycle as the platen ordinarily would automati cally advance, provision is made to cause the rocking open of the platen frame to vaccomplish this. An arm |2| attached to the machine frame, having a cam surface on its lower edge, is positioned to contact a roller |22 mounted on arm |08, as the platen frame moves clockwise around shaft l|05 as 'a center. The parts'are sopositioned that arm |08 is moved clockwise and the platen advanced asydesired.

Printing hammer mechanism the hammers which are held by trigger latches |25 (Figs. 1 and 5) secured to a shaft.| 26. The resetting bail 99 is actuated by shaft 3| through arm 98 and link 91. A downwardly extending arm |21 (Fig. 5), securely mounted to shaft |26, is given a'clockwise movement near the end of the rst half-cycle of operation. This movement is imparted by a link |28 (Figs. 1 and 5) pivoted to cam plate 10. n the first half-cycle of operation, the link |28 is moved forwardly. Part of such forward movement of the link |28 is idle due to slot |29 (Fig. 1) so as to allow thetype bar levers to be differentially set before 'the hammers strike. When the shaft |28 reaches the extreme clockwise position, all the trigger latches` will be rendered ineffective and the hammers will strike in response to the tension of springs |24.

Special mechanism is provided for locking selected hammers, as will be described.

Improvements in the mechanism for resetting Aand locking the printing hammers are a feature of this invention and will now be described.

Securely mounted on shaft |30 (Figs. 1 and 5) are a series of printing h'ammerresetting cams -|3|, one cam being provided for each hammer. Each cam has a radial eminence for every 90 degrees of its circumference save one, as shown in Fig. 5. The cams are secured on shaft |30 so that the' quadrants of the cams' circumferences having no eminence are set in spiral fashion on the shaft, so that, as the shaft |30 is turned, each quarter turn will find three of the cams with 'an eminence contacting a surface on the lower arm of the printing hammer levers as shown in Fig. 5, while the second hammer from the left is not 'contacted by a cam. Those levers 3| being contacted by cams cannot print when trigger latches |25 are sprung, while the hammer, second from the left, that is not lretained by a cam, will be actuated by its spring. A sprung hammer will be reset on the next cycle of the machine operation by the reseting bail described, and locked in reset position as the latch triggers are set in the nal phase of movement of cam (Fig. 1). All the hammers inoperative during a machine operation are thus locked against movement and all the operated hammers are restored. The type group selecting cam shaft and the hammer selecting cam shaft each move one,

quarter of a revolution for each machine operation.and are synchronized, so that each is in the same phase of movement. This is shownin the drawings by Figs. 4 and 5, Where the type group second from the left'and hammer second from the left are both conditioned to be operative. Both cam shafts are driven by gear 13 (Fig. l), whose driving mechanism has been described. Through an intermediate gear |33 mounted on stud |34 (Figs. l and 2), gear |32 is driven with the same angular movement as gear 19.

As with the column type group or selecting cams, the hammer selecting cams may be' ar,-

Platen rocking mechanism Another novel feature of this invention is the mechanism for rocking the platen assembly to open-throat or front-feed position, combined with the Smith type of machine herein described.

The platen is carried in a framework 'composed of side plates |35 (Figs. 8, 9, and 10) and tie rod |36, further supported by transverse operating and pivot shafts to be described. This same framework carries a rear paper table divided into two chutes, the bottom chute |31, for material inserted from the front, and the-upper chute |38, for'material inserted from the rear for a work sheet or tally sheet used to record a number of transactions, said rear-inserted material being inserted and rolled around the platen as in a standard typewriter. l

The side plates |35 Aof the platen framework are each mounted on a yoke |39 (Figs. 8 and 9) by platen shaft |40 and studs |4|, said yoke being pivoted on rock shaft |05, so that the platen frame will rock back and forth between limits established by a stop bracket |42 engaging shaft |40-on the closing or counter-clockwise movement and stop |43 engaging stud |4| on the opening or clockwise movement. Hereafter the position of the platen assembly will be referred to as` closed when in the counter-clockwise position as shown in Fig. 8, and as open" in the clockwise position ready for insertion of record material from the front as shown in Figs. 9 and 10.

The cylindrical platen I3 is rotatably mounted on shaft |40, hereinafter 4referred to as the platen shaft. An adjustable eccentric cam |10, secured by a screw |1| in an elongated hole in the stop |42, adjusts Vthe position of the stop to allow for diiference in paper thickness.

Projecting from the right side of the frame |39 is a stud |44 (Figs. 8 and 9) on which is mounted a sleeve, (not shown). Secured to the inner end of the sleeve is an arm |45, and secured to the outer end of the sleeve is another semi-circular arm |45, forming together an offset bell crank lever.

Arms |45 and |46 are rigidly fastened together by means of the above-mentioned sleeve. On the sleeve, between the two arms, is pivotally mounted a hook |41 adapted to hook over a stud |48, attached to the right frame of the machine, when A the platen assembly is in the open position as shown in Fig. 9. Pivotally mounted to the rear of the right platen frameis an arm |52 resting on a stud |49 projecting from hook |41. Arm |45 has a roller |50 projecting laterally from its outer end, which is lpositioned to ride the upper cam edge of arm |52 when the parts are positioned as in Fig. 9, but to be prevented from riding the cam edge when the surface |5| of hook |41 is riding the stud |48 as in Fig. 8.

When it is attempted to rotate arm |46 clockwise onstud |44,. the roller |50 bears down on arm 52 and, throughstud |49, bears down on hook |41, which bears on stud |48. This locking of parts results in a torque around shaft |05. Surface |5| is arcuate to shaft |05 as a center,

so no straining .of the parts occurs as the whole ming surface so that the parts are locked open in the position shown in Fig. 9, with the hook |41 engaged with the stud |48.

It should be noted that after the notch of arm- |41 engagesthe stud |48, the rotation around shaft as a center ceases, and rotation is thereafter around stud |44. Reverse movement restores the parts to the position shown in Fig. 8, with the aid of spring |54 to pull hook |41 from stud |48. A handle 53 (Fig. 13) 'is provided to manually operate the opening and closing of the platen assembly. The parts of the platen assembly are so weighted that their center of gravity is to the forward side of shaft |05 when the platen assembly is closed and to the rear side of shaft |05 when the platen assembly is open. Consequently, the platen tends to stay in either closed or open position. Momentum imparted to the assembly will carry it open or'closed' then clockwise in one machine operation. A ,stud |56 (Fig. 8) at its outer end is adapted to engage `hook 51 (Fig. 8) of a link |58 pivoted at its upper end to arm |46. A spring |59, when actul and raises the link |58 on the last half of the machine cycle just after the printing has taken place. The upward movement of link |58 givesA arm |46 the necessary lift to open and lock open the platen assembly. The rear side of link |58 is developed to ride a stud |60, which holds the hook |51 in engagement with the stud |56 until near the end of the upward movement, when the link |58 curves forward and kallows spring |6|, then under tension (Fig. 8), to disengage hook |51 from the stud|56. The platen is always closed by the handle |53, leaving the hook in the position shown in Fig. 8.

The means -willnow be described for causing hook |51 to move forward to engaging position. Shaft 80 (Figs. 1, 4, and 8), on which thevtype lever selecting cams are mounted, has secured on its right `end a cam |82, which turns 90 degrees at each machine cycle, as do the other cams secured thereon. At a point 180 degrees from the position shown in Fig. 8, the cam |62 will push forward on spring-|59 andfplace the hook |51 yieldingly in the path of stud |56. By placing the cam |62 in the properv quadrant, the platen may be automatically rocked open after the printing occurs in any@ desired column. It is obvious that a plurality of cams may be used if it is desired to open the platen assembly after printing operations in a number of chosen columns.

A manually set cam is provided if it is desired to open the platen assembly after every machine operation. An open-throat" key (Figs-2 and 8) on the keyboard, upon being pressed down, causes, through a pivotal connection, a counter-clockwise rotation of bell crank lever |63 (Fig. 8) around pivot |64. -This causes link |65 to move to the rear, which link is connected at its rear endwith a bell crank lever |66 pivoted on shaft 80. The upper arm of the bell crank lever |66 is a cam which performs the same function as cam |62, when in operating position. Spring |59 is wide enough to engage the two cams which are side by side. The open-throa key, being depressed,

' before.

opens the platen at the end of the next machine l operationl by exactly the same means actuated.

by cam |62. 'I'he key can be locked in depressed condition by engaging slot |61 with the casing of the machine if it is desired to have the platen open at every subsequent operation. s

Front feed guide chute |68 (Fig. 10) extends from the rear to the front of the platen and beyond, leaving clearance for paper between it and the platen, in both the `open and closed positions. When the platen is rocked open, the front papertable |69 (Figs. 8, 9 and is rocked away from the platen, as will be explained, so that work material may be inserted from the front between it and the platen .into the open-throat of the chute andonto the back paper table. Pressure rollers |80 are carried in cradles |8| on arms' |82, whiclrirollers press against the platen through aperturevswin the lower paper table |68. -Arms |82 are secured on shaft |83, which shaft is turned clockwise on the closing of the platen assembly by an arm |84 (Fig. 11) engaging a bifurcated arm |85, which is an'extension of arm |45, mentioned The pressure roller construction is the same as that in the Christian patent and application referred to above, and reference is made to them for further description.

The front paper table |60 (Fig. 10) is secured to arms |86 pivoted on platen shaft |40. At the upper ends of arms |86 are studs |81 adapted to travel in curved slots |88 in brackets |89 which are attached to the framework of the machine.`

outwardly as in a toggle vjoint and makes it` necessary to provide the curved slots |88 in which the studs can move. p'

A paper bail |90 (Figs. 9 and 10) attached Vpivotally to the platen frame lside plates and resting lengthwise along the top of the platen, yieldingly held there by springs |9| serves to hold the work sheet or tally sheet around the platen so as not to interfere with material inserted through the front feed chute. z While the forms of mechanisms herein shown and described are admirably adapted to fulfill the objects primarily stated, it is to be under stood that it is not intended to conne the invention tothe one form or embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the lclaims which follow.
